Abstract

The invention relates to a preparation method of building walls, furniture, metal light-resistant water-based coatings and adhesives. Add water, emulsifier and methacrylic acid to the reaction system, stir for 30 minutes, add A monomer, emulsify, heat up to 80 ° C and drop Add the initiator, drop the reaction for 1~2h, then add the light-resistant material and 2-(3,4-dihydroxyphenyl)ethylamine, stir and react for 2h to obtain the core layer emulsion; Add monomer B and initiator dropwise, stir and react at 80°C for 2h after adding dropwise, then add crosslinking agent, react at 75~85°C for 2~3h, cool down to 50°C, add emulsifier, react for 60min, add more The light-resistant material and 2,4-diamino-6-hydroxypyrimidine are reacted at 70°C for 1 hour, and the pH value is adjusted to 7-8 by adding ammonia water to obtain the light-resistant water-based paint and adhesive for building walls, furniture, and metal , the preparation method can not only greatly improve the light resistance of the acrylate resin, but also improve the film-forming yellowing defect of the acrylate resin emulsion.

Description

technical field [0001] The invention relates to a method for preparing a light-resistant water-based paint and an adhesive, in particular to a method for preparing a building wall, furniture, metal light-resistant water-based paint and an adhesive. Background technique [0002] Coatings and paints sprayed on the surface of internal and external walls, furniture, and metal appliances are in direct or indirect contact with human beings all the time. Toxic and harmful paints have always threatened people's health. Because the field of use is often exposed to sunlight, because the sun’s rays contain a large amount of ultraviolet light harmful to colored objects, its wavelength is about 290-460nm, these harmful ultraviolet light changes the color of the paint through chemical oxidation and reduction. [0003] The largest market for acrylic resin coatings is car paint. In addition, it is widely used in light industry, household appliances, metal household appliances, aluminum prod...
